Title: Frequency adjusting method of piezoelectric vibrator
Inventor: NAKADA HOZUMI
IPC: H03H3/04
Filed: 1983-12-27
Abstract: PURPOSE:To improve the workability and the chemical and physical characteristic of electrodes by arranging a piezoelectric vibrator formed with base electrodes and the electrodes themselves in an electrolyte, connecting the positive terminal of a DC power supply to the base electrode of the piezoelectric vibrator and connecting the negative terminal to the electrode. CONSTITUTION:The piezoelectric vibrator 12 formed with the base electrode and the electrode 13 are arranged oppositely in the electrolyte 11 of silver cyanide. The positive terminal of the DC power supply 14 is connected to the base electrode of the piezoelectric vibrator 12 and the negative terminal is connected to the electrode 13. Thus, the metal forming the base electrode is dissolved into the electrolyte as ions and drawn to the electrode 13 to which a negative voltage is applied. Thus, the mass of the base electrode is decreased and the resonance frequency of the piezoelectric vibrator is increased. Then the entirely same stability is obtained even after the frequency is adjusted by forming the base electrode with a chemically and physically stable method such as vacuum vapor deposition.

Title: Bus controller and information processor provided with the same
Inventor: TSURUTA HIDEYO
IPC: G06F12/04
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To enable a high-speed data transfer and the simultaneous processing of both endian by judging the endian by seeing the higher-order bits of an address, and switching the endian of data corresponding to a byte aligner. SOLUTION: In the address map of 32 bits, the area to be allocated to the external space is bisected for two pieces of endian data. When performing access to the external space, an address space discriminator 112 judges which area of endian is accessed, every time of access by seeing higher-order 3 bits A31-A29 of 32-bit addresses A31-A0. The information on this endian is transmitted to a byte aligner 111. Based on three kinds of information on external data bus width, endian and the length of transfer data, this byte aligner 111 selects any path required for transfer so as to rearrange the order of bytes.

Title: Data recorder
Inventor: KOZUKI SUSUMU
IPC: G11B20/12
Filed: 1987-10-06
Abstract: PURPOSE:To shorten the retrieval time of data and make data editing easy by equipping with a second mode to record repeatedly address data to show a tape address many times onto respective tracks by a revolving head. CONSTITUTION:The title device has the second mode to form many parallel tracks on second areas a1 and a3 existing extendedly in the longitudinal direction of a tape-shaped recording medium T in parallel with a first area and at the same time, to record the address data to show the tape address onto the respective tracks many times repeatedly by a revolving head H1. Consequently, revolving heads H1 and H2 cross obliquely the respective tracks of the second areas a1 and a3 in the condition of running the tape-shaped recording medium T at high speed but since the address data are repeatedly recorded onto the second areas a1 and a3, the address data can be obtained from every part of the tracks. Thus, even when the tape-shaped recording medium T is run at high speed, the address data can be surely reproduced and a retrieval speed increases. Since the address data recorded on the second areas a1 and a3 can be used as the absolute address of the tape-shaped recording medium T, the editing of the data becomes easier.
